PLOW.

SPECIFICATION forming Vpart of Letters Patent No. 267,648, datedNovember 14, 1882.

Application filed August 31. 41882. (No model.)

To alt/whom it may concern:

Be it known that I, PEDRO A. FOMINAYA, a citizen of Havana, Cuba, haveinvented certain new and useful Improvements in Plows,

' 5 of which the following isaspecificationeferencebcing had therein tothe accompanying drawings.

My invention relates to a wheel-plow for breaking up land. 1o I willtlrstdescribe the construction of the parts, their arrangement andconnection with each other, their operation, and the advantagesresulting therefrom, and will then designate the parts and combinationsconstituting the invention.

In the accompanying drawings, Figure l is a side view ot' the plow. Fig.2 is a top view lof the plow. Fig. 3 is a rear end view.

y The letterA designates the beam; B, the cutzo ter; O, the mold-board;D, the landside.

The letterE designates a single wheel, which is in the rear and on-aline with the cutter. This wheel is intended to run 011 the bottom .oftheA furrow, and serves when plowing as a steering-wheel, and when notplowing, but

when moving the plow, serves as a motorwheel on which the plow rides.

At the front end ofthe beam are two wheels, F, mounted on an axle, G,which has at its 3o center an upright bolt, H, passing loosely throughthe beam. This bolt may partly turn in its bearing ill the beam, andthereby the axle and wheels-F are so pivoted that they may be turned tochange the direction of the moving plow. The bolt H and beam A havevertical movement with respect to each otherthat is, if the wheels be onthe ground, the front end of beam has anl up-and-down movement bysliding ou the bolt, by which (as will 4o be presently explained) theplow may be lifted entirely from the ground.

`An upright post, I, is secured to the rear end of the beam, and to thispost the landside D is bolted.

4 5 Two partly circular lor segment-shaped bars, J, are placed uprightand alongside ot' each other, with a space between. One end of each ot'these bars is attached to the beam, and the other end of each to the topof the post. The

5o bars have holes for the insertion of a loose pm, 2c.

A lever, K, is pivoted at L on top of the beam. A portion of the rearend occupies the space between the two uprightsegment-shaped bars, andsaid lever is then bent upward atl, V and then by an angular bendprojects to the` rearward, as lat 2. This rear projecting part l2constitutes a handle. The front end ot' the lever loosely grasps thebolt H between two collars, 3, rigidly fixed tothe bolt, whereby, while6o the bolt may turn freely in the grasp ot' the lever, the said bolt orthe end ot' the beam will be moved vertically up'or down, according asthe lever is raised or depressed. lf the hau-` dle'2 atthe rear end ofthe lever be depressed, 65 the e'ect is to lower the front end. ot' thebeam, and thereby tip the plow-pointand cutter down to enter the ground.It' the said handle be raised, the effect is to elevate'the front end ofthe beam and cause the weight to rest upon 7o the wheels, and therebylift the plow entirely from the ground, in which position the plow may,by means ofthe three wheels, be moved over the road to any place.

Two horizontal arms, N are rigidly attached 7 5 to the post and projectrearward. Each arm has a bearing, through which the tiller-post P ot'the steering-wheel turns. This Vtiller-p'ost cannot, however, moveendwise through the bearings. The lower end ot' the tiller-post is Sobifurcated, as at 4, to straddle the' steeringwheel, 'and a pin, 5,passes through the bifurcation on each side of the wheel and through thehub ofthe wheel.

A pivot-pulley, It, is' mounted on the upper 85 part of the tiller-post,and a chain, S, passes partly around this pulley, and one end ot' thechain is attached to one end ot' a horizontal guide-bar, T, on top ofthev bolt H, and the other end of the chain is attached to the oppo- 9ositeV end of the said guide-bar. By this arrangement it will be seenthat when the tillerpost and steering-wheel are partly turned, the frontwheels and axle arelikewise turned,there l by changing the direction inwhich the plow is to move..

Two guide-levers,U,are attached to the tillerpost, and by these thelatter may be turned, and they also serve for raising the plow. Y

A set-screw, V, is provided in one of the horizontal arms, and the endof this screw may' be made to press against the tiller-post and,

IOO

' 2 i acacia by holding the latter rigid, prevent lateral B, the frontwheels and their axle, an upright motion of the steering-wheel when theplow is in operation.

It will be seen I dispense with the two plowhandles usually employed.Thus, when not lifting the plow, at least one and frequently both handsmay be free. When my plow reaches the end of a furrow, an upwardmovement of the lever-handle raises the plow off the ground. The leveris kept up by placing the loose pin w through holes in the upper part ofthe segment-shaped bars under the lever. The plow may then be moved onlthree wheels to the point where the front end of the next furrow is tobe made. Any direction can be given to the plow by the three wheels andsteering device. The np-and-down movement ot' the lever regulates .thedepth ot' the cut which the plow will make in the land. By my plow morework can be done in4 heavy soil with less manualattendance than any plowof which I have knowledge.

The shape of the cutter, mold board, and landside are immaterial so faras the working of my invention is concerned, for whatever may be thealleged advantages of plows of different makes, or plows having cutterand moldboard shaped differently from mine, this invention is applicableto all ot' them.

Having described my invention, I claim and desire to secure by LettersPatent of the United States- 1. In a plow, the combination of the beambolt, H, attached to the axle passing loosely through the beam andhaving on top a horizontal guide-bar, T, a pivot-pulley, R, at the rearend of the plow, and a chain, S, passed around the pulley and havingitsends attached at opposite ends of the guide-bar, as set fo'rth.

2. In a plow, the combination ot' the front wheels, a bar, T, to guidethe front wheels, a rear steering-wheel, E, having a tiller-post, a.lpivot-pulley on the tiller-post, and a chain passed around the pulleyand having its ends attached at opposite ends ofthe guide-bar, as setforth.

3. In a plow, the combination, with the moldboard and landside, of asteering-wheel at the rear, a tiller-post directly connected to thesteering-wheel, and guide-levers attached to the tiller-post, as setforth.

4. In a plow, the combination of the beam A, an upright post, I, securedto the rear end ot' the beam, horizontal arms N, rigidly attached to theupright post, a tiller-post having its bearings in the arms, and asteeringwheel adapted to be guided by the tiller-post, as set forth.

In testimony whereof I atlix m y signature in presence of two witnesses.
